The 'Wake Me Up' hitmaker has spoken out about Robin Thicke's controversial number one single and says he's glad his collaboration with dance artist Avicii was competing with it in the charts because it provided a "balance" to the "immoral" messages.

He said: "There's really no problem with the song ['Blurred Lines'] aside from the subtle innuendos that are made glaringly apparent in the music video.

"It's an important thing what we do with music. Music is a spiritual experience whether you want to admit it or not, music opens your senses and has been used historically as a conduit to your inner psyche.

"So when we do this as musicians ... to open people up and then to dump trash into them, is to me, no matter what your religion is it's sacrilege, it's immoral."

The 35-year-old star, who has seven-month-old daughter Mandela with his wife Maya Jupiter, thinks the lyrics in 'Blurred Lines' provides a confusing message to young boys and girls about what is and isn't acceptable.

He explained to BANG Showbiz: "The machismo, the misogyny, the violence, the disrespect ... I just don't think it's necessary and I actually think it's damaging to the psyche of young girls and it's damaging to the psyche of young guys who sort of fantasise in this world of being macho and sexist."
